Flashback® White Self-Adhesive Silicone Sponge Tape & Gasket Strip

Typical uses include electrical enclosures, control panels, access panels, HVAC equipment, lighting installations, industrial equipment, door and hatch seals, automotive and transport applications, marine applications, cushioning, vibration reduction and anti-rattle protection.

Apply to clean, dry, stable surfaces that provide suitable adhesive contact. Adhesion should be tested on the actual material, especially plastics, powder-coated surfaces, low-surface-energy materials, rough finishes and demanding outdoor or high-temperature applications.

1. Make sure the application surface is clean, dry and dust-free.
2. Remove oil, grease, loose paint and other contamination.
3. Test adhesion on the actual surface before full installation.
4. Peel back the yellow release liner gradually.
5. Apply the tape without stretching it.
6. Press firmly along the full length to create consistent adhesive contact.
7. Allow the adhesive time to bond before placing the tape under compression, load or environmental exposure.
8. For sealing, aim for approximately 30% compression and do not exceed 50% compression.

What temperature can it withstand?

The tape is rated to -40°C to +200°C. The silicone sponge itself has a typical stated range of -60°C to +230°C with intermittent resistance to +250°C, but the adhesive is rated to -40°C to +200°C, and a self-adhesive tape performs only as well as its weakest layer. If your application will sit close to +200°C for long periods, test it first.
